Inflation in Non-de Sitter Background with Coherent States
E. Yusofi, M. Mohsenzadeh, M. R. Tanhayi
We use the excited coherent states built over the initial non-de Sitter modes, to study the modification of spectra of primordial scalar fluctuation. Non-de Sitter modes are actual…
Radiation effects on particle's trajectory in the linear level
M. Fathi, M. Tanhayi-Ahari, M. R. Tanhayi +1
In this work, we first obtain the linear form of the scalar self-force and then, the effect of self-force on the particle's trajectory is considered. In de Sitter space-time, withi…
Auxiliary "massless" spin-2 field in de Sitter universe
H. Pejhan, M. R. Tanhayi, M. V. Takook
For the tensor field of rank-2 there are two unitary irreducible representation (UIR) in de Sitter (dS) space denoted by and [1]. In the flat limit…
Conformal linear gravity in de Sitter space
M. V. Takook, M. R. Tanhayi, S. Fatemi
It has been shown that the theory of linear conformal quantum gravity must include a tensor field of rank-3 and mixed symmetry [1]. In this paper, we obtain the corresponding field…
Linear Weyl Gravity in de Sitter Universe
M. V. Takook, M. R. Tanhayi
In this paper we obtain the linear Weyl gravity in de Sitter background. Its linear form in five-dimensional ambient space notation has also been obtained. From the group theoretic…
